Ore Blending as Mine Scheduling Strategy to

2013-1-1 · The challenge is how to do ore blending as part of mine scheduling. The mining concept are, ore that is mined from pit will be stored in five different ore stockpile. Products will be produced from ore blending in stockpiles. As run scheduling simulation, best scenario elected show 12.91 MWMT total material movement in first five years.

Ore Stockpiling – Why are we doing this again?

2016-4-28 · 3. Surge Control: Surge piles may be used in cases where the mine may have a fluctuating ore delivery rate and on some days excess ore is produced while other days there is underproduction. The stockpile is simply used to make up the difference to the plant to provide a steady feed rate.

Mine stockpile design to minimise environmental impact

2014-5-15 · Putting the ore onto stockpiles before shipment serves a double purpose. The stockpiles provide a quantity buffer between the arrival of ore trains from the mine and the more irregular departure of ships. But of just as much importance is the effect of stockpiles in blending out variations in ore composition.

2022-2-2 · About ore blending & stockpiles: Since the function of the stockpile is to act as an ore reservoir rather than as an ore processor, the action of forming a stockpile should have as little effect as possible on the material. Several undesirable effects are produced by discharging the material from too great a height above the stockpile.

2009-8-26 · ORE TRACKING: Mining equipment implemented for ore extraction is optimal for selective mining. Material from the pit is transported to various stockpile destinations. These include high-grade (>13% Zn), medium-grade (9 - 13% Zn), low-grade (4 - 9% Zn) and marginal (1 - 4% Zn) ore stockpiles. Limestone (Ca >28%) from the pit is mined for plant acid
